These barren fields in the north-east of the kingdom of Arc are mighty battlefields of the past, and the ground is still befouled by magical warfare. Even centuries (or millenia!) later remains of the battles can be found in bits of jade lying beneath the toxic earth. Rarely those excavating the area even find mighty magical artifacts that have been buried for centuries.
Treasure hunters can often be seen setting up camp in the area in hopes of finding the next big treasure trove of the area. Scavenger Lord Kree is said to have made his first riches digging through these fields, he still finances expeditions to excavate the area.
